MACHINE FOR AND PROCESS OF FORMING RINGS 0R RIMS 0N GLASS BOTTLES.

SPECIFICATION forming part of Letters Patent No. 238,090, dated February '22, `1'881.

Application lcd October 6, 1879.

To all whom tt may concern Be it known that I, WILLIAM C. Cook, `of Pittsburg, Pennsylvania, have invented anew and useful Improvement in Machines andProcesses for Form-ing Rings or Rims on Glass Bottles; which improvement is fully set forth inthe following specification, `reference being had to the accompanying drawings.

Similar letters of reference indicate correspending parts.

My inventionrelates to the formation of rims or rings Von the mouths of bottles and similar glass vessels; 'and it consists, first, in `reheating the blow-over without removing the ar-ticle from the mold, and then, when itis in la plastic condition, molding it into a rim `or ring around the bottle-mouth; and,second, -in the apparatus by means `of which I fcarry said operation into effect. y

To enable others skilled in the art to make and use `'my invention, I will no'w describe it by reference to the accompanying drawings, in which- Figure 1 isa perspective view of the apparatus. Figs. 2 andS-are sectional viewsof the plunger. Fig. 4 is an end View of the plunger of Fig. 3,-and Fig. 5 is a perspective view of the pipes which supply the a'rand gas for reheating the blow-over.

A is a revolving table, placed and capable of revolution `upon a suitable bed, A', and provided with handles A2, for turning it thereon;

`On the table A are two two-part molds, B and B', the said parts being hinged as at bf". Each moldhas a bottom plate, b4, having a disk on its upper surface with larin g edges, around which the two parts of the molds close in the usual way, being provided with handles Pivoted to the vtop of the postGyare four I tubes, c c c c. The tubes c are designed to supply gas for `the reheatin g of the blow-over, and the tubes c the air or oxygen that maybe necessary to the proper combustion of the gas. For this purpose the outer ends of tubes care provided with tubular rings c, larger than-the mouthgof the mold, which are perforated on the under side to cause jets of gas to encircle and impinge upon the blow-over which projects from the mouth of the lnold. The outer ends Vof the tubes c' are provided with flat or disk rings c5, having a double row of perforations, one inside and the other outside of the rin gci, so that the air or oxygen from the tube c shall be projected on both sides ofthe stream of gas from the tube c, enveloping and com'mingling with it and insuring its perfect combustion. The tubes c and c are preferably united and held in their proper relative positions by a central bar, c6. The gas is supplied tothe tubes@ through the pipes c3, and the air to the tubes c through the pipes c2, said gas and air being und-er pressure and controlled by valves at c", or at other convenient point.

D is a IiXed post or upright, having a socket, D3, in its upper end, in which is placed the upright or post Dl of a swinging frame for sustaining the pressing-tools that form the lip lof the bottle.

Extending laterally from the post D are two horizontalarms or gibs, D2 and D4, the lower of which, D2, slides vertically on the post D-, bein g sustained and adjustable to suit the 'height of the mold used, by a long screw, E, which is provided with suitable nuts c e', one above and the `other below the upper gib, D4. Pivoted to each side of the gib D2, atf, near the outer end, is an arm, F, which arms extend diagonally upward and backward, and above the gib D4 are pivoted to the opposite ends of a short shaft, f3. On the shaft f3 is a lever, f, to the outer end of which is pivoted the upper end of the plunger-shaft, as at f5. The lever f has a handle, f4, for operating the plunger.

The tool H is composed of several parts. Attached to the Vstock H by a screw', h3, is an outer cylinder, H'. H is bored out at h5 for the reception of an The lower end ofthe stock I OO inner cylinder, H4, which is' secured to it by a screw, h4. Inside of the bore h5 the stock has a deeper and narrower bore, h5, for the reception ofthe upper end of the plunger H2, which is secured therein by the rod hl, extending across the head andthrough a slot, 71,5,in the plunger. The slot h2 is made long to permit ot' a certain vertical movement of the plunger in and independent of the movement of the stock H. The plunger H2 is turned down to a smaller diameter at the middle section, to afford room for a spring, h, which, being placed on it, bea against the stock H at one end, and against 25 shoulder, hi, on the plunger at the other, an tends to hold the plunger out to its `iullest eX' tent, as shown clearly in Fig. 2. Placed be tween the cylinders H and H4 is an intermediate cylinder, H3, held in place by and having an enlarged diameter at its lower end to receive the collar H5 on the lower end of the cylinder H4. The cylinder H3 extends below the collar H5 and forms an annular recess, h2, around the lower end of the plunger H2. Around the cylinder H4, between the lower end of the stock H and the upper end of the cylinder H3 is a spiral spring, h', which holds the cylinder H3 down upon the shoulder H5, but permits it to have a limited vertical movement in the cylinder H.

The operation of the above-described apparatus is as follows: During the operation of blowing the bottle the mold is closed, as at B. Projecting from the hole 117, at the close of the blowing operation, will be the blow-over, which is a ragged broken tube of glass attached to the unfinished neck of the bottle. Heretofore the usual custom was to remove the bottlefrom the 1nold,reheat itin the gloryhole of the furnace, and iinish it with a handtool. I throw open the top section, b5, (see mold B,) and bring the ends c4 and c5 of the air and gas tubes over the mouth of the mold aud reheat the blowover without removin gthe bottle from the mold. When the glass is sufticiently plastic I turn the air and gas tubes aside and bring down the tool. The tapered plunger H2 enters and forms the interior ot' the mouth, and spreads the glass out into the annular recess, h2, so as to be pressed into a proper bead, rim, ring, orlip around the mouth. If there is too much glass in the blow-over, the springs 7L h will permit the plunger H2 and cylinder H3 to give back sufeiently to accommodate it. The spring H6 then retracts the tool, and the mold is opened and the bottle removed.

For vials and light ware a head or knob, G, (shown in broken lines in Fig. 1,) maybe used for pressing instead of the lever f and its connections.

If it is desired to make a pouring-spout on the bottle a former, J, may be used, Figs. 3 and 4.

The stop c is designed to stop the rotation ot' the table .A at the right place to bring the molds under the plunger.

The table A may be stationary, and the tool H made to swing over both molds, if desired.

The duplication of the mold is merely to increase the Arapidity of the operation, as the bottle may be blown in one while that in the other is being iinished. A pulley, i, is provided to rotate the plunger, if desired, in the production of threads on or in the bottle-mouth. In that case there would have to be a suitable coupling-connection between the lever f and rotating plunger, to permit the rotation of the plunger. Such a connection is a wellkuown mechanical contrivance.

The part d is a guide sliding'baek and forth on the gib D2, and designed to adjust the tool accurately to the molds.

This invent-ion is applicable to the linishing of the ends of jars and many other articles which are blown in molds. It will, of course, be necessary to change the forming-face of the plunger to the particular size and shape ot' the articleto be operated upon. I

The advantages of my invention consist, mainly, in saving the heretofore necessary step of removing the article from the mold, reheating, and finishing by hand, and, in most cases, of gatheringfresh glass to form the ring. Instead of this I complete the article without removing it from the mold, and, as it is iinished by a machine, Isave time in the operation, and obtain an increased production.

Heretofore the uniformity of the product depended upon the skill oi' the workman. I can adjust my machine so as to obtain a much more uniform result than is possible by hand.

Heretofore the article was liable to become distorted by being removed and inished away from the mold. This cannot happen in the use of my invention, because the article is supported duringthe entire finishing operation by the mold.

Where a gas which requires little or no oxygen to be supplied for its combustion is used the air-pipes c may be dispensed with.

More than two molds may be arranged on the table A, it desired.

What I claim as my invention, and desire to secure by Letters Patent, is f l. The process of forming rings or rims on the mouths of glass bottles and similar articles, consisting in reheating the unfinished mouths of the same and subjecting them to forming-pressure while still in the mold in which they were blown, substantially as and for the purposes described.

2.
